Step 1: Figure out how much you need to hem
Try on the pair of jeans and roll the cuff up to how much you want off the bottom. Then carefully take off the jeans--keeping the cuff. Measure how much you cuffed. These jeans needed 2 1/4 inches hemmed. Pin the jeans carefully measuring at each point you pin. (I pinned every 2 inches and measured exactly 2 1/4" at each pin).
Important: When you are pinning the jeans make sure to carefully line up the stitching/seams on the sides of the jeans. You can see in the picture below that I pinned the jeans exactly lined up with the gold stitching.
Step 2: Sew!
This is going to feel weird. But trust me! You will place your needle next to the original hem. You will sew RIGHT NEXT to the original hem. Stitch on the RIGHT side of the hem (the farthest from the bottom of the jean). Sew all the way around the cuff. Repeat on the other leg of the jean. If you have trouble sewing over the seam with your machine try using a thicker needle. I choose to use my hand and turn the wheel on the side of the machine manually when I go over the thick seams on the sides of the jeans.
Important: Make sure you do not sew through the front and back sides of the jean (not that I'm speaking from experience)!
Step 3: Turn the legs of the jean right side out.
Step 4: Press the jeans flat so they aren't bulky or if you have hemmed a ton (like 5 inches or something) you can just cut off the excess portion. They may fray when washed if you do cut them off. That's why I just iron them really well on the bottom.
You can see in the picture where we sewed...but just barely. Believe me, nobody will be able to tell when you are wearing your jeans.
